Question

What is the difference between variation and evolution?

Answer 1

Variation:

1. Variations are variances in characteristics that exist among individuals of a population.
2. They are caused by the various types of genes found in a species or community.

Evolution:

1. Evolution, on the other hand, is a progressive process in which an organism or a component of an organism develops into a different, typically more complicated or better form.
2. New species emerge as a result of evolution.

Difference between variation and evolution:

Variation	Evolution
1. The observable change exhibited by individuals within the progeny and species is referred to as variation.	1. Evolution is described as a change in the heritable characteristics of a population through generations.
2. It occurs through mutation and recombination.	2. It occurs through natural selection.
3. Variation encompasses both long-term and short-term changes.	3. Evolution is a long-term process.
4. It might be reversible (epigenetic variations) or irreversible.	4. It is a permanent transformation that occurs through generations.
5. Variations produce distinct forms, or alleles, of genes.	5. Evolution results in the formation of a new species.
